Royal Caribbean offering late check out cabins but at a cost

Royal Caribbean are offering customers the chance to keep their cabins for late check out on the day of dis-embarkation.

At the moment this is being offered on a trial basis on the Adventure Of The Seas to see how popular and how practical this is.

Customers book on board and pay for the privelege of keeping their cabins longer.

Many customers find it difficult when they have flights departing for home late afternoon and early evening when they have to disembark and then hang around either at the airport for hours or dragging their luggage to the nearest restaurant so they can pass the time.
This seems to me to be a good alternative if customers can keep their cabin longer and at least give them some choices, yes it will be at a price but is the price to pay better than the inconvenience.

Do you think this is a good idea ?... Would you pay for this? and do you think that other cruise lines should eventually offer this facility?
